The Columbia River Quarantine Station, now known as the Knappton Cove Heritage Center, is a historic site in Knappton, Washington. The station provided fumigation and quarantine services to maritime vessels at the port on the Columbia River from 1899 to 1938, and is the sole remaining quarantine station on the West Coast of the United States as all others were burned for fear of contamination. It was added to the National Register of Historic Places in 1980.
